selftests/bpf: Enlarge select() timeout for test_maps
0Day robot observed that it's easily timeout on a heavy load host.

# Failed sockmap unexpected timeout
not ok 3 selftests: bpf: test_maps # exit=1
# selftests: bpf: test_lru_map
# nr_cpus:8
-------------------
Since this test will be scheduled by 0Day to a random host that could have
only a few cpus(2-8), enlarge the timeout to avoid a false NG report.
In practice, i tried to pin it to only one cpu by 'taskset 0x01 ./test_maps',
and knew 10S is likely enough, but i still perfer to a larger value 30.
